f fiat tire whereby it becomes possible to drive the vehicle tothe nearest service station without injuring the tire.

Another object is to provide an attachment formed of sections which, whenk not in use,

= can be compactly stored but, when assembled and in use, will be properly held relative to eachother. n

A further object is to provide an attachment that can be quickly and easily attached z to a wheel without requiring the use of any supplemental fastening means.

With the foregoing andv other objects in View which will appear as the description proceeds, the invention resides in the combir nation and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosedl may be made within thev scope of what is claimed without departing from the spirit of the invention.

In the accompanyingdrawings the preferred form of the invention has been shown.

In said drawings, f

Figure 1 is aside elevation of the attachment and the wheel rim to wl'iieh itl is applied.

Figure 2 is a transverse section through the structure shown in Figure 1.

Figure 3 is a perspective view of one end of one of the tread members. v

Referring to the figures bycharacters of reference, 1 designates each of a series of segmental tread members. Each member 1 has an arcuate tread portion 2 the outer sur face of which is preferably transversely conveXed while extending from the inner surface at the center thereof is a web 3 4extending throughout the lengthof the section.

i The ends ofthese webs can be vbeveled as shown` at i and oneend of each section can have its treadportion offsetinwardly tol provide a forked seat 5 adapted to receive andA lapthe nearend ofthe neXt adjoining section.

VThe sections areso proportioned that when ,j

they are assembledend to end they will Aform a ring the diameterofwhich will be equal to or slightly greater than the diameter of an iniiated tire on the wheeljto which the attachment is to beapplied. f f Y Extended inwardly from ,the web 3 ,of each section are radial arms 6 each of which is provided in one yside-withl a recess 7 adapted to receive` and straddle theannular iiange 7" at one side of a Wheel rim R. That end wall of each recessnearest,thetread portion of the attachment is preferably concave asv indicatedatS' so ,as to-constitute a seat whereby thrust will be transmitted between the rim andthearm6.-.j if, j A The rim-engagingfportion of each arm 6 islocated at one side thereof. Thisrim engaging portion includes a yshort linger anda long arcuate finger v8. the two Iingers being spaced apart rso `that the outer finger will engagethe outer periphery ofl'fla'nge kc" while the .long arcuate finger 8, Will engage the inner periphery of saidv flange. Thus when the portion 2 of each tread member 1 is swung laterally relativeto the rim R, these fingers will tend to pinch the flange-7a so that the attachment will not slip circumferentially along the rim. Formed on vthelother side offeacharm is av reinforcing rib 9 terminating 'in anr ear 10 in which is i formed va slot 11i. This slot is open at oneV vend and is obliquely disposed so .thatav hook is produced.which'will engage in the eye 12 of a'bolt 13.- v.One of these bolts is pro vided for each armj 6 and all of the bolts are extended throughdugs 14 extended laterally from a, 'ring 15.v The diameter of this ring is lessthan the internalr diameterof rim R. ling nuts 16 or the like engage the bolts and bear upon lugs 14C. Y

` wheels of 'i different diameters.

In practice the bolts are in engagement with the lugs but the tread sections of the attachment are disengaged from the bolts Y andcan be stored one upon the other or side moved forwardly Vor backwardly to bring one of the sections 1` beneath the wheel whereupon the remaining section 1 is placed in position and its arms 6 are engaged by the bolts provided therefor. All of thel bolts are vthen tightened. It will be apparent by referring to Figure 2 that when the bolts 13 are tightened they will tend to swingsthe Aportion 210i the tread members l laterally away from the rir'n R. Thiswilleause the fingers 7 andf'8 to 'pinch the' iflange#l as heretofore'explained.

\ By following the procedure outlined, the sections l' will-be; held 'rigidly to' the rim 5R and the attachment "will be'supportedconcentric with the rim. -Thus said attachment will relieve the flattire Vfromthe load that would otherwise-be supported thereby and the vehicle 'can bedriven any Adesired distance without causing injury to the tire.

p Obviously the attachments can beniadeof d'iffeil'ent sizes to'adapt them for Vuse 'with While it is prefered to make each Vatvc-a'ch'ment with -its treat-l1 portion in three' sections, the' number can obviouslybe changed to nieetthe' requirements. Y

The parts can be vmade ofianyde'siredlmetal o'f the requisite'strength and'weight. i

By providing a device suchasf-described, it be'cm'es unnecessary to 'use j aeksland rsimilar devicesor lifting aV wheel tofrelievetlie tire carried thereby. y
